3 Company Product Specification Eti Soda has a partnership structure whose 74% share belongs to Ciner Group, being a leading organization in mine, energy and media sectors in Turkey and whose 26% share belongs to Eti Mining Corporation being a government entity. The company is the first and only natural soda production plant within Europe. ETİ SODA INC. was established in 1998 to extract, operate and bring in economy trona mine reserves, found during routine coal boring operation carried out in Beypazarı, Ankara in In order to reach the vision of becoming a world leading brand, Eti Soda is continuously improving product and service quality via ISO 9001, ISO 14001, ISO 22000, OHSAS 18001, ISO/IEC management systems and certifications. To provide the safety of the chemical products exported upon the human health and environment, ETİ SODA has completed the regulations determined in the REACH Legislation, which is effective in the European Union Countries. Sodium Carbonate Dense Soda Ash, Sodium Carbonate also known as disodium carbonate is a chemical substance white in colour and its aqueous solution is clear and colourless (chemical formula Na₂CO₃). Use Areas Glass Chemical industry Soap and detergent Eco-labelling (ISO Type I) : N/A Paper Flue gas treatment Water and waste water treatment Sodium Bicarbonate Trona mine, located in Beypazarı district of Ankara, is extracted from the ground by the solution mining method, which is a safe and environment friendly operating technique. The trona solution is taken into the monohydrate process and converted to the Sodium Carbonate and Sodium Bicarbonate products. The products of ETI SODA, which are used in many sectors such as glass production and baking powder, are exported all over the world, especially to European countries. Technical Grade Sodium Bicarbonate also known as sodium hydrogen carbonate is a chemical substance white in colour and its aqueous solution is clear and colourless (chemical formula NaHCO₃).

4 System Boundary Supply Transport Downstream Processes The upstream process includes raw materials production and the manufacturing of the primary and secondary packaging. Processes Pre-treatment Calcination Evaporation Trona Solution Crystallisation Hydro-extractor System Boundary The scope of the core module is defined by the organizational boundaries and includes all activities which the manufacturing organization is in control of. In this LCA Study the core process includes transportation of raw materials to production plant, impacts generated by diesel burned in the core process, impacts due to the electricity production according the country energy mix. of trona solution also operated by ETi Soda and considered under core processes. Energy consumption during the trona solution delivery to the manufacturing plant has been included into core processes. Materials for Packaging Packaging Distribution Use Phase End of CO2 Life H20 The International EPD System has adopted an LCA calculations procedure, which is separated into three different life cycle stages: module (from cradle-to-gate); module, manufacturing processes (from gate-to-gate); Downstream module (from gate-to-grave). Downstream Processes According to PCR, it is not mandatory to declare any quantitative information about the use and end-of-life phases. Therefore, downstream is excluded from the system boundary. Sodium Carbonate and Sodium Bicarbonate have many different applications and are often used as input materials to other production processes. It is difficult to allocate an environmental burden from the use phase to the chemical input. Also, the end-of-life management depends on the application and location of the use and disposal of the chemical. No relevant data is available for the use and end of life phases of the products manufactured by Eti Soda. The lifecycle of the products encompasses the following main stages: Extraction of natural resources, Transportation of natural resources, Processing and refinement of natural resources into chemical intermediates, Manufacturing of the chemical product, Manufacturing of packaging materials. EPDs within the same product category but from different programmes may not be comparable. 6 7

5 LCA Information Environmental Performance LCA Statement This study has been conducted in accordance with ISO and standards the requirements stated in Product Category Rules (PCR) document for BASIC INORGANIC CHEMICALS N.E.C., and also ISO The inventory for the LCA study was carried based on the 01/01/ /12/2016 production figures for Sodium Salts as Sodium Carbonate and Sodium Bicarbonate from Eti Soda manufacturing plant. Data Collection Specific data (primary data) was used for the Module and was gathered from the Eti Soda Manufacturing Plant. The manufacturing processes were modelled and Life Cycle Impact Assessment stage was conducted in SimaPro software v8.4 with Ecoinvent v3.3 database. Scope This EPD evaluates the potential environmental impact of Inorganic Sodium Salts manufactured by Eti Soda. The environmental impacts include Sodium Carbonate and Sodium Bicarbonate production processes during their life cycle from raw material supply to factory gate. According to the PCR document, the functional unit is 1000 kg of sodium salts with packaging. The System boundary includes, and Downstream processes with a cradle-to-gate approach. There has been no cut-off rule conducted for this LCA study. Allocation The raw materials are purchased from different locations of Turkey and from Spain via different transportation ways such as roadway and seaway. Therefore, transport has been allocated per tonnage per mileage for products transported to manufacturing plant. Transport data within the plant has been also allocated per 1 ton of product. There has been no allocation conducted for energy consumption as electricity consumption was provided by the company specifically sodium carbonate and sodium bi carbonate processes. Calculation Methods Materials and energy uses have been determined from life cycle inventory results from SimaPro outputs. Potential environmental impacts are calculated with the CML-IA baseline V 3.04, ReCiPe Midpoint (H) V1.13 / Europe Recipe H, USEtox (recommended + interim) V1.04 / Europe 2004 methods in SimaPro software.
